Science is humanity’s ongoing attempt to understand 1 the Universe works. Whether in the form 2 meticulous research, ingenious insight, or unexpected discoveries, the search for truth continues to challenge, often 3 (lead) to more questions than answers.

Throughout history, humans have always been driven to understand the workings of the world. In their quest for knowledge, philosophers in ancient Greece were the first 4 (try) to explain what they observed. However, many of their ideas were 5 (accurate), as their philosophical method lacked any experimental evidence.

Thales of Miletus in the 6th century BCE, for example, proposed that water is the primary substance of the cosmos, as he 6 (realize) that water is essential for life and that it exists on land, sea, and in the air. Two centuries later, Aristotle wrote widely on scientific subjects, from physics and biology to astronomy, laying the foundations for much of the work that has followed. However, he 7 made fundamental errors, such as arguing that 8 (heavy) objects fall faster than lighter ones, because he relied on thought and argument rather than empirical proof.

Despite being some distance from a reliable scientific method --- in 9 a hypothesis is proposed, systematically tested, and evaluated on the strength of the results --- 10 early thinkers made vital findings, Halley’s comet was observed in China in 240 BCE. and some 300years later, Zhang Heng explained eclipses and drew up an extensive catalog of stars.

文章大意：这是一篇说明文。文章主要介绍了对早期宇宙中垂死星系的活跃的超大质量黑洞的研究。这些活跃的超大质量黑洞的出现与宿主星系的变化有关。银河系的恒星有着年龄差距，而其他星系比如椭圆星系的恒星则年龄相同。研究人员对超大质量黑洞的存在和对其宿主星系的影响进行了猜测，同时希望通过研究更遥远的星系获得进一步的理解。

An international team of astronomers used a database combining observations from the best telescopes in the world 1 (detect) the signal from the active supermassive black holes of dying galaxies (星系) in the early universe. The 2 (appear) of these active supermassive black holes is related to changes in the host galaxy. This means a black hole could have far reaching effects 3 the evolution of its host galaxy.

The Milky Way Galaxy 4 we live includes stars of various ages, including stars still forming. But in some other galaxies, 5 (know) as elliptical (椭圆的) galaxies, all of the stars are old and about the same age. This indicates that early in 6 (they) histories elliptical galaxies had a period of rich star formation that suddenly ended. Why this star formation stopped in some galaxies 7 not others is not well understood. One possibility is that a supermassive black hole disrupts(瓦解) the gas in some galaxies, 8 (create) an environment unsuitable for star formation.

To test this theory, astronomers look at distant galaxies. Due to the limited speed of light, it takes time for light to travel across the void of space. The light we saw last night from an object 10 billion light years away 9 (travel) for 10 billion years to reach Earth. Thus the light we see today shows us what the galaxy looked like when the light left that galaxy 10 billion years ago. So looking at distant galaxies is like looking back in time. But the longer distance also means that distant galaxies look 10 (small), making study more difficult.

The discovery     3    (make) by a team     4    (consist) of scientists from the Massachusetts Institute of Technology (MIT) and high school students     5    were seeking a natural water filter(过滤)—one that would help communities in developing countries that do not have     6    (accessible) to modern water filter systems.
The     7    (research), led by Professor Rohit Karnik, decided to turn    8    trees for help, because they could allow liquid to flow through, while blocking out air bubbles.
They began by cutting 1.5-inch-wide sections of tree bark from the branches of a white pine tree. The people related then tested the wood’s filtering ability by pouring water containing red dye particles of different sizes through. To their     9    (amaze), they found that it was effective in trapping all the particles. Greatly     10    (encourage), the team conducted another experiment, this time with water that contained bacteria. Sure enough, the sapwood held back 99% of the bacteria, allowing only 1% to flow through.
